THE trains that will run on high-speed tracks once the Channel Tunnel rail link is completed will be built by Japanese Bullet Train manufacturer Hitachi, the Government announced yesterday.

Transport Secretary Alistair Darling said Hitachi was the preferred manufacturer for the 140mph trains that will operate on the Kent franchise.

The order is expected to be for about 30 six-carriage trains, to be introduced in 2009.

The trains will run from Kent to St Pancras station in London, where a Eurotunnel terminus is being built in time for the completion of the second stage of the Channel Tunnel rail link in 2007.

The trains will play a crucial role in the so-called javelin shuttle to support London's 2012 Olympic bid by moving spectators from central London to the Olympic Park in Stratford, east London, in less than eight minutes.

The trains will have security cameras, passenger information systems, comfortable seats and facilities for the disabled.

Alistair Dormer, business development director at Hitachi Europe, said: ''This is a firm endorsement of our international reputation for delivering world-class rail solutions and of our commitment to the UK rail market over the last five years.

''We believe we have a highly relevant proposition for the UK and are committed to delivering safe, reliable and cost-effective solutions to the whole of the European rail market.''
